The present invention relates to improvements in document photographing machines and particularly to mechanism for controlling the operation thereof and indexing mechanism therefor.

The invention comprehends improvements in control mechanism for document photographing machines to provide for the control of the lights and film feed thru the provision of a single control lever operable by a plurality of actuating means engageable therewith at different positions and arranged in relation to the document feed mechanism so that the actuating members for the lever can be moved into disengaged inoperative position or removed from the machine Without interfering with the mounting and assembly of the lever in the machine.

The invention provides suitable control means operable to render the document feed mechanism inoperative whenever more than one document is fed at one time and means for varying the operation of the control means according to varying thicknesses of documents. A control of the document feed is provided for stopping the feed of documents Whenever the light support is not in operative position.

The invention provides a control to stop the feeding of documents whenever more than one thickness of documents or sheet material is fed at the same time having an arrangement for varying the control by document thickness thru manual operation of suitable setting means adapted to set the control for passing documents of different thickness for each setting,

The invention further comprehends the provision of an indexing mechanism for document photographing machines arranged to display desired indexing material for photographing simultaneously with documents arranged so that a photographic record of the index for the document is made upon the film with the pictures of the document. The indexing mechanism provides for a plurality of different and independent indexes so that an indexing number; district number or zone number; date; information rcgarding location, such as city, town and the like; and information regarding governmental and company names; branches and divisions may all be photographed with the document in successive order on the film. Control mechanism is provided for setting the various indicia displaying mechanism in a convenient manner so that the operator of a document photographing machine may change the setting of any indicia by the operation of suitable control and setting mechanism.

This invention provides improvements over the document feeding, control and indicia displaying mechanisms disclosed in co-pending application Serial No. 472,359, filed January 14, 1943. The general construction of the document photographing'machine employing the present invention is disclosed in this co-pending application and the structure shown herein ma be substitutedfor. the corresponding structure shown in said application. The document feed rolls and supporting structure therefor, corresponds to that shown in a co-pending application on document feed construction filed simultaneously herewith, Serial No. 528,681, Patent No. 2,377,525. Other features of the device are claimed. in divisional application No. 895, filed on January 7, 1948. The document photographing machine disclosed in both of the co-pending applications discloses a frame structure for supporting the various mechanisms of the machine having side walls at the front endsof the base portion for supporting the document feed, the illuminating means and the control mechanism for themachine.

Right and left-hand side walls I and 2 correspond to the side walls shown in the aforementioned applications. The document feed mechanism has-end plate 3 mounted in spaced parallel relation for supporting a plurality of spaced parallel arcuate guide bars 4, Fig. 20, to provide a. curved path for guiding documents thereover from the top to the bottom portions thereof in a manner disclosed. in the co-pending application Serial No..528,68l, filed simultaneously herewith. End plates 3 mount a plurality of feed shafts 5 carrying document feedrolls 6 rigidly mounted thereon in spaced relation and having the peripheries extending between arcuate guide bars 4" with a portion of the periphery of each feed roll extending beyond the outer periphery of arcuate guide-bars 4 for engaging and feeding documents over the outer edges of said guide bars. Feed shafts 5 are journalled in end plates 3 and at the right-hand ends, as shown in Fig. 3; the shafts project thru an opening in end plate I indicated at Tin-Fig. 1 where each shaft carries asmall gear 8 inter-meshing'with internal gear 80f main drive gear 10.-

Main drive gear it! is rigidly mounted on main drive shaft ll extending transversely across the frontof the machine between side walls 5 and 2 and beyond the outer side thereof, as shown in-Figs. 1, 3 and 5. A main drive pulley i2 is driven by an electric-motor, not shown, thru belt i3. Pulle I2. is mounted on a stub-shaft carried by side wall 5 and carries a pinion l4 intermeshing with gear l5 mountedion another stubshaft carried by side wall I and having clutch Cir a controlled driving connection with gear in; inter .meshing with the external gear teeth H on main drive gear 18.

The clutch control for the driving connection between gears 15 and 56 has a pair of clutch collar operating arms l8 carried by rod 59 rotatabl mounted in bearing bracket 26 secured to the outer side of side 'wall 5. A lever 25 is mounted on the end of rod 59 at the opposite side of the bearing from clutch collar operating arm 98, as shown in Fig. 1, and has the free end thereof connected with the armature of solenoid 22. The clutch is disengaged when the solenoid is energized. When solenoid 22 is not energized a coil spring 23 having opposite ends secured to lever 21 and side wall 1 respectively, as shown in Fig. 1, operates lever 2i to rotate rod 19 and maintain the clutch in engaged relation for driving main drive gear it in the rotation of main drive pulley l2 by the motor.

Upper and lower document guide units are shown in dotted lines in Fig. 1 at 24 and 25 respectively, and have fragmentary portions also shown in Figs. 3, 4, 5 and 20. These upper and lower guide members have a plurality of arcuate guide bars 26 mounted in spaced parallel relation between and supported by end members 2'1. Upper and lower guide members 24 and 25 carry a plurality of feed shafts 28 each mounting a plurality of document feed rolls 29 arranged to have the peripheries thereof extend between guide bars 26 and engage the peripheries of feed rolls 5. Feed rolls 6 and 29 are arranged in pairs for peripheral engagement to engage opposite sides of documents fed into the machine and move them between guide bars A and 26 from the top front portion of the machine through a photographing position for photographing the documents and feeding them outwardly from the machine at the bottom portion of the guide bars, in a manner disclosed in both of the aforementioned co-pending applications.

A supporting rod 36 extends through the upper front corners of upper guide member 2:2 and has the free ends detachably engaged in openings in side walls I and 2 for pivotally supporting upper guide member 24 in transversely extending relation between side walls 6 and 2. A suitable latch member having latch rods 3i secures the lower rear end of upper guide member 24 in operative position, as shown in Fig. 1. A pair of supporting rods 32 engaged in transversely extending relation through end members 2'] of the lower guide member 25 removably mounts the lower guide member in operative position between side walls 1 and 2. The feed rolls and feed roll shafts of upper and lower guide units 2 1 and 25 are mounted for radial sliding movement and are resiliently projected to maintain the peripheries of feed rolls 29 in feeding engagement with the peripheries of feed rolls 6 on feed shafts 5 of the main feed unit. End plates 3 have projecting portions mounted on supporting rod 33 secured at opposite ends in side Walls i and 2. The right-hand end plate 3 has an aperture in the central portion for engagement over a supporting stud carried by a portion of side wall I projecting toward main drive shaft 5 i as indicated in Fig. 1 at 7. This provides for detachable mounting of the main document feed unit between side walls I and 2. The path for feeding documents is arranged in concentric relation to main drive shaft 1 1 having roller bearing mountings in end plates '3. Documents enter thefeed' unit at the top as indicated at A, Fig. 1, and after passing through a semi-circular path past the photographing position are discharged at the bottom of the unit at B.

The left-hand end of main drive shaft H extends beyond left-hand side plate 3 as shown in Fig. 5 thru an opening in side wall 2. The lefthand end of shaft H has a reduced end 34 r0- tatably mounting clutch member 35 thereon having a worm gear 35 formed on the outer end intor-meshing with worm gear 3! carried by drive shaft for the film drive mechanism. The outer end of clutch member 35 has a rotatable thrust bearing mounting in bearing bracket 38 mounted on the outer face of side wall 2. A clutch member 39 has an annular flange for receiving the periphery of the clutch disc portion of clutch member 35 and a hub portion secured to main drive shaft ll between left-hand end plate 3 and side wall 2, as shown in Fig. 5. A clutch control ring as having a toothed outer periphery is rotatably mounted on rotatable clutch member 35 adjacent the clutch disc portion thereof and carries clutching rollers 4 l, as shown in Figs. 4 and 5. A clutch ring retaining disc 42 is mounted on the hub portion of rotatable clutch member 35 against rotation relative thereto and normally retains clutch control ring 4 in position for securing operation of clutching rollers ll. Resilient means connected between clutch ring retaining disc 42 and clutch ring 45 normally tends to rotate clutch rin 45 for engaging the rollers between clutch member 35 and the flange on clutch member 39 in clutching engagement for driving worm gear 3d from main drive shaft i l.

A link 63 has its upper end pivoted to side wall 2 as shown in Fig, 2, and at the lower end mounts r a laterally extending stud pivotally mounting the central portion of pawl 44 having one end formed to engage the teeth on clutch control ring and the opposite end connected by tension spring 45 to a pin :lt on control lever 47. The stud carried to a pin carried by side wall 2 forwardly of link 43 in order that the link will be resiliently moved so that the stud carrying pawl 44 will be engaged with side wall 2 at the front edge of the opening thru which the stud extends.

Control lever 41 is of irregular shape, has one end pivotally mounted on stud 49 on the inner side of side wall 2 and a clutch operating arm 51 provided with a stud for engaging the lefthand end of pawl 44, as shown in Fig. 2. Clutch operating arm is positioned to have the stud thereon disengage pawl 44 from clutch control ring it when lever ll is moved in a clockwise direction, as shown in Fig. 2. Lever 41 has an arm 5! for manual operation in controlling the machine in a manner that will be hereinafter described. An upwardly extending arm 52 on control lever ll has a laterally extending pin thereon for engaging and operating the inclined end of a bell crank lever 53 pivoted 0n bracket '54 mounted on side wall 2. A micro-switch is mounted on bracket 54 at the opposite end from bell crank 53 and is adapted to be operated by bell crank 53 in the operation of control lever 4! so that whenever control lever H is moved in a clockwise direction, as shown in Fig. 2, bell crank 53 will op- 6 erate micro-switch 55 to close the circuit con trolling the lights for illuminating the documents being fed through the photographic position by the document feed mechanism.

Dociunents being fed between feed rolls 6 and 29 in the semi-circular path hereinbefore mentioned engage and operate primary and secondary control fingers 56 and 5'1, as shown in Fig. 2, mounted on control shafts 58 and 55 respectively, rotatably mounted in end members 21 of upper guide unit 24. The left-hand ends of each of the control shafts 58 and 59 mount annular discs 60 each having an eccentric pin 6! mounted thereon extending toward the inside of side wall 2 and engaging against the edge portion of control lever t! at two different places, as shown in Fig. 2. When fed documents engage and operate primary and secondary control fingers 56 and 51 respectively, they are moved in a clockwise direction as shown in Fig. 2, rotating discs 50 and moving pins 8| to engage and rotate control lever i"! in a clockwise direction for operating microswitch 55 into circuit closing position and disengaging pawl 44 from clutch control ring 4!]. This closes the light circuit for illuminating documents passing through the photographing position and engages the clutch for feeding film so that pictures of the documents are taken as they pass through the photographing position. A stud 62 mounted on the inner face of side wall 2 extends inwardly through a slot in the upwardly extending arm 52 of control lever 4'1 and serves to limit its rotary motion on stud 49. A tensioned coil spring E53 has one end connected to stud 62 and the other end to pin 46 carried by control lever ll for normally moving control lever 41 into an inoperative position so that pawl 44 is engaged with clutch control ring 40 and the pin on arm 52 allows bell crank 53 to be operated to open the circuit through micro-switch 55.

Thus, when either the primary or secondary fingers are operated by a document being fed through the machine between feed rolls 6 and 29 as above described, control lever M will be moved in a clockwise direction, as shown in Fig. 2, micro-switch 55 will be closed for lighting the lights and clutch ring 40 will be released to provide for engagement of the clutch members and the feeding of film by the operation of worm gear N by worm gear 36 carried on rotatable clutch member 35.

A controlling device is provided for stopping the feed of documents in the event more than one document is fed at a time, which may be set for operation to stop the machine whenever any document of greater than a limited thickness is fed into the machine.

This double document control mechanism has the uppermost feed shaft 5 of the main feed unit provided in the central portion of its length with a center metallic feed roll 54 as shown in Fig. 20. The upper feed shaft in the upper guide unit 24 arranged in paired relation with the upper feed shaft 5 has a centrally located metallic feed roll thereon for peripheral engagement with feed roll 64 while the remaining feed rolls on this upper shaft do not have peripheral engagement with the corresponding feed rolls 6, as shown in Fig. 20. Opposite ends of the uppermost feed shaft 28 are mounted in bearing sleeves 65 carried by slidable blocks 5"! engaged between the spaced plates of end members 2']. Radially extending guide slots 68 in the plates of end members 21 slidably mount bearing sleeves 56 for radial movement and laterally extending pins 69 ,y I are slid'ably' engaged inslots 68 in end members 21.

At the right side of the machine the free end of pin 69 engages one end of a bell crank lever Ill pivoted at l! on a stud projecting inwardly from the inner face of side wall I while the upper end of bell crank it has a projection 12 engaging a thickness control cam #3. Thickness control cam 13 is mounted on the inner end of an adjusting shaft 14 having the central portion rotatably mounted in a bracket l secured to the outer face of side Wall E. The outer end of adjusting shaft 14 carries a knob "l6 adapted for manual rotation to adjust the position of eccentric 13. A ratchet wheel "H is mounted adjacent the inner end of knob '1 and has the free end of a spring actuated pawl i8 resiliently engaged therewith for normally -'holding adjusting shaft l' l against rotation. Pawl i8 is pivotally mounted on bracket 15, as shown in Fig. 21.

There are ten teeth on ratchet wheel 11 in order that pawl is will operate to normally hold the ratchet wheel against rotation by knob 16 in a predetermined position for each adjacent pair of teeth until the spring pressure of pawl 73 is manually overcome by positive manual rotation of knob 16. Knob it is in the form of an annular disc having a knurled periphery, as shown in Fig. 3, with a cylindrical portion adjacent the disc provided with indicia at 19 showing the position of thickness adjustment of knob '16. The numerals indicating the adjustment run from one to ten and represent thickness adjustments for sheets determining positions of adjustment where sheets of different thickness will be either fed through the machine or prevented from being fed by stopping the feed.

A bell crank lever 68, Fig. 4, is pivoted against the inner side of right-hand side wall i in front of the upwardly extending arm of hell crank lever 16, as shown in Fig. 4, on a stud projecting inwardly from side wall 1. One arm of hell crank 89 extends upwardly and has a pin 8! on the upper end extending laterally and engaging the forward edge of the upper upwardly extending arm of bell crank iii. The other arm of bell crank 80 extends rearwardly and has one end of a coil spring 82 connected to the end thereof. The opposite end of coil spring 82 is connected to one end'of lever 33 extending radially from document straightening shaft 3 carrying document straightening fingers 85 for engaging the leading edge of a document immediately after it is fed into the feed mechanism between rolls 64 and 85. When any part of the leading edge of a document engages fingers 85, rolls 34 and 85 will continue to feed the document until the entire leading edge engages all of the fingers 85 when further feeding of the document will move fingers 85 and rock shaft 84 against the tension of spring 82 until the straightened document passes under the ends of the fingers. The straightened documents will then be guided through the feed mechanism with the leading edges in transversely extending relation. Coil spring 82 also operates simultaneously to maintain bell crank 89 with pin 3? in engagement with the upper end of bell crank it? for maintaining projection 72 in constant engagement with the surface of eccentric T3. The lower end of bell crank "l0 extends rearwardly and the rear free end thereof engages above laterally extending pin 89 at the right-hand side of the machine on slidable block-El for holding the slidable block against upward movement.

It will be understood that the adjustment of knob 16 will vary the position of the end of bell crank to hold pin 69 in a position moved .inwardly to a greater extent than shown in Fig. 4, and may also be adjusted to provide for the movement outwardly beyond the position shown, according to the position of adjustment of the knob. This provides a fulcrum between the rearwardly extending arm of bell crank Ill and pin 59 at the right-hand side of the machine on which upper document feed and control shaft 28 carrying metallic feed roll 65 will be pivoted transversely in the machine as documents are fed between rolls 64 and .65. The left-hand end of upper feed and control shaft 28 with left-hand slide block 6! and pin 69 will be raised upwardly about the fulcrum on bell crank 16 to a small extent when a thin document passes between feed rolls 6i and 65 and to a greater extent when a thicker document passes therebetween. The movement of left-hand slide block 5'! and pin 69 is greater than the thickness of the document because of the diiference in leverage due to the distance between the fulcrum at the right-hand pin 68 on bell crank Ill and centrally located feed rolls'fi i and 65.

The movement of left-hand slide block 61 and pin 69 is therefore greater than the document thickness engaged between rolls 6% and 65 and is utilized to operate switch control bell crank 86 pivctally mounted on bracket 87 on the outside face of left-hand side wall 2. A short substantially horizontall extending arm 88 on bell crank 86 extends inwardly through an opening in side wall 2 and is formed with a lateral extension to normally engage the top peripheral portion of the projection 69 on left-hand slide block 57, Fig. 20. A coil spring 89 secured at one end to short arm 88 of bell crank86 and at the opposite end to a stud on the inner face of side wall 2 firmly maintains the end of arm 88 engaged with left-hand projection 59 to maintain feed and control roll 55 in resilient rolling contact with roll 6 3. The other arm 98 of bell crank 86 extends upwardly along the outside of lefthandside wall 2, as shown in Figs. 3 and 20, and has the free end provided with a lateral projection for engaging the operating pin of microswitch 9i mounted on the upper portion of bracket 87, as shown in Figs. 2, 3 and 20.

In the counter-clockwise rotation of bell crank 86 through the raising of pin 59 by a document engaging between feed and control rolls 64 and 55, it Will be seen that by controlling the position of the fulcrum for upper shaft 28 at the righthand end, the amount of vertical movement at the left-hand end of the control shaft can be utilized to actuate micro-switch 93 to close the circuit thereto and actuate control means for stopping the feed of documents whenever the document thickness is greater than the amount for which the knob is set. Micro-switch BI is connected in the electrical circuit with solenoid 22, so that whenever the switch is closed, the solenoid will be energized to disconnect and stop the feed mechanism from operating so that documents annot be fed through the feed mechanism beyond-rolls'fi l and 65. The action of the control is so rapid that only the leading edge of documents of a greater thickness than that for which the control is set will engage between feed and control rolls 64 and 65 before the feed mechanism actually stops. This provides for convenient manual removal of the documents at the top front portion of the feed mechanism by the machine operator resulting in the feed mechanism being restored to operation. so the operator can again feed the documents into the machine in proper order. This mechanism prevents the feeding of two or more documents simultaneously and also the feeding of documents that are folded or of a greater thickness than is provided f r by the setting of control knob I9. This control mechanism may control the operation of the feed in any suitable manner such as just described and shown in either of the co-pending applications hereinabove mentioned whether the feed of documents be manual or mechanical.

A lighting unit is provided for illuminating the documents so that the proper amount of light is reflected from the document into the camera for making photographs. This lighting unit includes a frame at hingedly mounted at the lower end on a transversely extending rod 95 mounted in side walls I and 2, as shown in Fig. 1. Lighting unit frame 95 has a lamp housing 9'! carrying a plurality of lamp bulbs in transversely extending relation arranged to project light toward the photographing position at 98 between the adjacent ends of upper and lower guide units 24 and 25 when frame 95 is in the closed operative position, as shown in full lines in Fig. 1. This frame is movable to an open position to provide access to the document feed mechanism so the upper and lower guide units 24 and 25 can be removed or upper guide unit 24 hingedly moved to an upper open position as disclosed in the aforementioned co-pending applications.

Frame 85 carries a light indicator means, indicated at 99, adapted to indicate when the lights are operating and also to indicate when one or more lamp bulbs is burned out, as disclosed in the aforementioned co-pending applications. Frame 99 has an upward and forwardly extending portion at the upper free end thereof carrying the upper ends of light indicator means 99 and at the upper left-hand corner thereof, as shown in Fig. 2, carries a laterally projecting stud Iilfl. When lighting unit frame 95 is in the closed operative position stud I99 projects transversely across the upper edge of left-hand side wall 2 for engaging bell crank lever I95 pivotally mounted on stud Hi2 extending outwardly from the upper edge portion of side wall 2. The upwardly eX- tending short arm of bell crank ill! has one end of coil spring ii -3 connected therewith and the opposite end connected with pin H34 on side wall 2 positioned to the rear of stud I92 for normally moving bell crank MI in a counter-clockwise direction, as shown in Fig. 2.

A stud I95 projects laterally from side wall 2 for limiting the counter-clockwise movement of bell crank II)! by spring Hi3 so the end of the hooked portion I03 of bell crank lEli will be operated to engage projection till on the end of upwpardly extending arm 99 of bell crank 88 to rotate bell crank 86 in a counter-clockwise direction. as shown in Fig. 3, to operate micro-switch 9! for closing the circuit. This operation of micro-switch 95 to close the circuit and maintain it in closed condition occurs whenever frame 95 is moved out of the operative position where pin Hit normally engages the upper edge of cell crank Ill! as shown in 2. Bell crank it)! normally has hook end Hi9 below the upper end of projection IN. This operation of bell crank iii! allows the free end of projection iii? to extend into the space between hook end I96 and the arm portion of bell crank IEJI extending out wardly from pivot stud I02. It will therefore be seen that it is necessary that the lighting unit frame 95 be secured in operative position before documents can be fed through the machine.

The document indexing feature of the present invention provides document indexing drum IIIl located between left-hand end wall 3 of the main document feed unit and left-hand side wall 2, as clearly shown in Figs. 3 and 5. Drum IIU includes an annular disc III having a central opening receiving the hub portion of clutch member 39 for bearing engagement thereon as shown in Fig. 5. A sectional cylindrical sheet metal rim I i2 is secured on the periphery of disc III at a plurality of positions for cooperation to provide the supporting structure for the several indicia displaying mechanisms.

Friction discs I I3 engage against opposite faces of annular discs III about the hub of clutch 39 so that a movable clutch disc I I4 slidably mounted on hub 3Q may be resiliently actuated to move against one friction disc i I3 and move annular disc III with the other friction disc against the annular flange on the left-hand end of clutch member 39, as shown in Fig. 5. A collar H5 is mounted on the right-hand end of clutch member 39 against rotation relative thereto and has an annular flange formed with openings slidably receiving rods i9 secured to movable clutch disc H4. Compression coil springs II! are mounted on rods H6 between the flange on collar H5 and movable clutch disc IM to normally maintain frictional engagement between clutch member 39 and annular disc III of indicia drum III) to normally rotate drum I It! with main drive shaft II.

Drum II I] carries a number displaying unit I29, a date unit I2I, and two location designating units I22 and I23 respectively, located in different circumferential positions about drum H9, as shown in Fig. 4.

The structure of numbering unit I29 is shown in Figs. 4, and 14 to 17.

Numbering unit I29 has two brackets H4 and I25 bolted together on opposite sides of annular disc III with offset free end portions in spaced parallel relation from each other and disc III in registry with an aperture in disc I i I. The offset free ends of brackets I24 and I25 have bearing openings therein axially aligned with the aperture in disc ill for rotatably receiving opposite ends of shaft I26. Shaft I 28 includes a tubular socket member I 21 mounted on the left-hand end thereof rotatably engaged in bracket I 25. Socket I2? is rigidly mounted on the end of shaft I26 and has the free end formed with slots I28. A ratchet wheel I29 is rigidly mounted on tubular socket I21 for rotation therewith and is located against the inner face of bracket 25 acting as a washer to limit endwise movement of shaft I25 in the bracket.

A unit number wheel I39 is rigidly mounted on shaft I26 adjacent ratchet wheel i129, as shown in Fig. 14, for rotation with shaft I26. Tens, hundreds, and thousands number wheels indicated by the numerals I3I, H2 and I33 respectively, are rotatably mounted in successive order on shaft I26 with tens number wheel I M adjacent units number wheel I39.

The several number wheels are separated by pinion discs I34. Each pinion disc I34 is engaged between a pair of adjacent number wheels and has a central opening engaged over hub I26. Pinion discs I34 are attached to supporting bars I35 connecting all Of pinion discs I34 together for holding them against rotation with shaft I26 and the number wheels. An arm I35 extending laterally from the lower portion of the offset end of bracket I24 engages the inner supporting bar I35 and holds pinion discs I34 against rotation. Each pinion disc I34 carries a gear pinion I31 rotatably mounted in bearing brackets thereon with the pinion extending through an aperture in the pinion disc. One pinion I3? is mounted in each disc and has inter-meshing engagement with a gear on the hub of an adjacent number wheel. The tens, hundreds and thousands number wheels I3I, I32 and 133 respectively, each has a gear I38 formed on one end of the hub portion thereof inter-meshed with the adjacent pinion I37. The gear IE8 is illustrated as being formed on the end of the hubs of the several number wheels directed toward the unit number wheel I38. The opposite ends of the hubs of all of the numeral wheels are provided with a pair of number wheel accumulator teeth I39, each adapted to engage the adjacent gear pinion I31 and upon each rotation of the number wheel advance the next number wheel a sufficient amount to advance the numeral displayed thereby one digit. In this way shaft I26 may be rotated to display the digits zero and 1 to 9 inclusive, in successive numerical order and then to operate the tens number wheel to move the display of the digit zero thereon out of position to display the digit one. In this manner each of the number wheels advances the display of the digits thereon in numerical order. The number wheels may be reset to Zero by means of resetting spring Mil. Resetting spring I40 is mounted in recessed portions of shaft I26 shown in Fig. 14. A plurality of resetting fingers I4I on spring I40 extend circumferentially and radially and have the free ends resiliently engaging the inner faces of the hub of number wheels I3I, I32 and I33 so that when shaft I25 is rotated in a direction opposite that during which the number wheels will accumulate numbers in numerical order as above described, fingers I4I will engage resetting shoulders I42, Fig. formed at the zero position of the digits on each number wheel, and reset all the number Wheels with the digits in corresponding position so that the zero digit on all of the number wheels may be displayed through a slot I43 in cylindrical rim I I2, Fig. 4.

The tens, hundreds and thousands numbers wheels are held in digit displaying position for displaying one of the digits on the periphery thereof through slot M3 by means of pinions I37 which may be provided with a suitable spring pressed retaining device for normally retaining the p'inions against rotation in pinion discs I34 of a character well known in the art. Shaft I26 is normally held against rotation by means of a pawl I44 pivotally mounted at its central portion on stud I45 carried by annular disc III, as shown in Fig. 4. One end of pawl I 44 is formed with an angularly extending end portion adapted to engage the ends of the teeth on ratchet wheel I29 for holding shaft I26 against accidental rotation. A coil spring I45 having one end connected to a pin on annular disc I I I and the other end secured to the free end of pawl I44 is normally tensioned to hold the angular end of pawl I44 in engagement with ratchet wheel I29. This operation will hold the unit number wheel, as well as the remaining number wheels in position to display one of the digits on each through slot I43 in cylindrical rim I I2.

An advancing mechanism is mounted on annular dis-c III for advancing the number wheels one digit at a time. For this purpose, an advancing lever I4? is pivoted intermediate its ends on pivot stud I43 extending laterally from disc III. A laterally extending operating pin I49 is mounted on the outer end of lever I4! with the free end projecting outwardly beyond theplane of the edge of cylindrical rim H2 in parallel relation to shaft II toward the inner face of side wall 2 for engagement with a digit advancing control mechanism. The opposite end of advancing lever It? has one end of advancing pawl I50 pivoted thereon and the opposite end positioned to engage one of the teeth on ratchet wheel I29. A pin I52 mounted on annular disc III acts to guide pawl I58 and limit oscillating movement of lever It? in both directions on stud I48 to bring the free end of the pawl into engagement with one tooth for operating the ratchet wheel to rotate shaft I26 an amount sufficient to ad- Vance the unit numeral wheel one digit. A coil spring I52 has one end secured to guide pin NH and the other end secured to pin I53 on the free end of pawl I58 for normally holding pawl I50 and advancing lever I41 in the position shown in full lines in Fig. 4 at one "limit of their relative movement ready to be engaged by a suitable operating device to move advancing lever I47 on its pivot and operate ratchet Wheel I29. Projection I5I on advancing lever I41 engages pin I5I to limit counter-clockwise rotation of the lever. The mechanism is designed so that pawl I542 will engage one tooth and. rotate ratchet wheel 529 only a sufiicient distance to advance um't numeral Wheel I30 one digit when lever I4! is rotated in a clockwise direction. Then lever I41 engages pin I5! limiting its rotation in a clo kwise direction.

The dating unit IEI is shown in Figs. 4, l8 and 19.

Dating unit I2i has a bracket I60 mounted on the right-hand side of annular disc III at one end and has the opposite end offset in spaced parallel relation to the disc opposite an aperture provided in the margin of the disc to accommodate the dating unit. A shaft iiiI has one end rigidly secured to the offset end of bracket I69 and projects laterally therefrom, as shown in Fig. 18. The free end of shaft IBI is formed with a reduced extension I62. Sleeve IE3 is rota'tably mounted on shaft ItI and has an inwardly extending annular flange I64 in the outer end apertured to rot-atably engage on the reduced extension i2 of shaft I6I. A coil spring IE5 is mounted on reduced extension I62 between the shoulder formed by the end of shaft ISI and inwardly extending Jannular flange I6 1 for normally moving sleeve I53 endwise on shaft I-BI until annular flange I6 3 engages stop pin I68. The outer end of sleeve I63 is provided with recesses III'I for receiving a setting device. It will be noted that sleeve ItB and tubular socket I21 have the same size and are adapted to be engaged by the same setting device in a manner that will be hereinafter described.

A month indicator drum I68 is rotatably mounted on shaft I-BI at the inner end of sleeve IE3 adjacent bracket ltd. Month indicator drum I58 has a polygonal disc I69 rigidly secured thereto with thumb disc we having the periphery serrated. Thumb disc I19 is larger in diameter than drum I68 so that its periphery may be manually engaged to set drum I68 in a position to display the desired month of the year th ru slot III in rim I I2. The opposite end of sleeve I63 rotatably mounts year indicator drum I72 having a polysonal disc I13 mounted on the outer side thereof and thumb wheel I14 secured to disc I13 having a diameter greater than the diameter of drum I12 for manual engagement and rotation of year indicator drum so that it may be set to display the desired year indication through slot I'lI in cylindrical rim H2.

Between month indicator drum I88 and year indicator drum Il'2 there are two day indicator wheels I15 and HE, respectively. Each day indicator Wheel has the periphery provided with digits zero to nine and is rotatably mounted on sleeve I63. Each day indicator wheel I15 and :16 has a polygonal disc I11 rigidly secured thereto. It will be noted from Fig. 18 that day indicator wheels I15 and 115 have the adjacent ends of the cylindrical outer portions opening toward one another with the supporting disc portions at the opposite ends. This provides a space within the Wheels for controlling the setting thereof. the purpose of setting the day indicator wheels each is provided with setting pins H8 extending inwardly from the outer edge of the supporting disc portion for the Wheels into the space inside the cylindrical portion of the wheel. Setting pins I18 are in parallel relation to shaft IBI and the ends terminate in spaced relation to each other when they are in aligned relation.

A setting pin I19 is mounted in the central portion of sleeve H63 in radially extending relation so that it will engage with one set of setting pins I18 depending upon the position of the sleeve on shaft I6I relative to Wheels I15 and I16. In the position indicated in Fig. 18, spring I65 holds sleeve I63 at the outer limit of its movement on shaft I6I with setting pin I 19 in position to engage setting pins I18 on day indicator wheel I15. By rotating sleeve I63 the desired day indication on wheel I15 may be set into position to be displayed through aperture I ll. Should it be desired to set day indicator wheel I15, this is accomplished by sliding sleeve I63 inwardly against the tension of spring I65 until setting pin I19 thereon is disengaged from the setting pins on wheel I 15 and positioned to engage setting pins I18 on wheel Il'fi. Sleeve IE3 is then rotated to set wheel I15. In this way wheel I16 may have the desired date indicating number set to be displayed through aperture I1I As shown in Fig, 19, each day indicator wheel has 3 setting pins I18 thereon to facilitate the setting of the day indicator wheels in a convenient manner.

A pivot pin I mounted on bracket Hill projects laterally and has the intermediate portions of holding pawls I8I pivoted thereon in spaced parallel relation. The outer ends of pawls ISI extend between wheels I68, I12 and at opposite sides of Wheels I15 and I16, as shown in Fig. 18, to engage th'e peripheries of the several polygonal discs I69, I13 and I11. Coil springs 82 corresponding in number to the number of pawls ltll each have one end anchored to an end of one of the pawls I8I and the opposite ends secured to laterally extending pin I83 mounted on an extending portion of bracket I 60. Springs I82 are normally tensioned for retaining the opposite ends of pawls I8I engaged with the several polygonal discs to maintain the discs in a position where a flat portion on the disc will be engaged by the pawl for holding each of the several discs with their at tached drums and wheels in a position to hold a month, year and day indication of the desired date in exposed position through aperture l1I in cylindrical rim II 2.

Location designating units I22 and I23 are of For 14 similar construction. These units are illustrated in Figs. 4 and 10.

Each unit includes a bracket I84 having one end portion bolted to the right-hand side of circular disc I I I and the opposite end portion offset to the right of the circular disc and extending in spaced parallel relation to the disc in alignment with an aperture in the margin of the disc. A shaft I85 is mounted in the central portion of the offset end of each bracket and extends through the aperture in the disc toward the opposite side. An indicia supporting cylinder I86 is rotatably mounted on shaft I85. The end-of each cylinder adjacent bracket I84 has a polygonal disc IEl'l secured thereto With a thumb disc I88 adjacent disc I81 at the inner end of the cylinder located next to bracket I84. The periphery of each cylinder is provided with a suitable covering, holders or the like, for carrying the desired indicia to be displayed for each position of the cylinder corresponding to one of the polygonal faces on polygonal discs I81. A pawl I89 is provided for each cylinder pivoted intermediate its ends on bracket i8 5 with one end engaging polygonal disc I8l between the end of drum 586 and thumb disc 38. Engagement of the end of each pawl I89 between the end of cylinder 5 86 and thumb disc I88 retains the cylinder in assembled rotary relation on shaft I85 against detachment. Coil springs I90 secured at one end to the free ends of pawls I89 and at the opposite ends to bracket I 84 hold the ends of pawls I89 engaged under tension with polygonal discs I8? for retaining cylinders I86 in position to display the indicia on the respective cylinders through slots 95 and E82 formed in transversely extending spaced relation in cylindrical rim 5 I2 opposite the peripheries of cylinders I86. Cylinder I86 of location designating unit :23 has the end shown in Fig. 4 directed toward the left-hand side of the machine, formed with slots E93 about the portion adjacent shaft I85 in the same arrangement and same order as slots I51 of the dating unit and slots 523 of the number displaying unit for receiving a setting member to be described.

The left-hand side of annular disc III, as shown in Fig. i, has three stop pins secured thereto, one indicated by the numeral l94 adjacent location designating unit I23, one indicated at I95 adjacent date unit ml and the third I96 adjacent number displaying unit I20, each adapted to be engaged by a mechanism to be described, for stopping rotation of the disc in order that the unit adjacent to the stop pin may be engaged by a setting member and its setting adjusted. Each of the pins I94, I95 and 95 have the free ends extending beyond the plane of the left-hand end of cylindrical rim N2 of indicia drum Hi3 so that they may be engaged by the control mechanism for stopping rotation of the drum. Each of these stop pins is located at different radial distances from the center of the drum, stop pin I94 being at the greatest distance, stop pin 595 being at a distance slightly less from the center than pin I94 and stop pin I96 being at the shortest distance from the center of the drum or main drive shaft Ii.

A control mechanism is provided for conveniently controlling the operation of indicia drum I I9 and for setting the numeral units thereon in a convenient manner. This mechanism is disclosed more particularly in Figs. 2, 3, 4 and 6 to 13.

A control plate 258 is mounted on the inner face of left-hand side wall 2 at the front upper cor- 20!, as shown in Fig. 6.

her portion and has aninclined upper edge carrying a laterally extending guide plate Elli mounted in inclined inwardly extending relation with the upper surface flush with the inclined upper edge of control plate 200.

A push-button control slide 202 has the upper end projecting through a slot in guide plate 295 adjacent plate 2% with a push-button on the upper end thereof positioned above guide plate Push-button control slide 232 is arranged in inclined relation in the machine perpendicular to guide plate 25! and has the lower end slotted to slidably engage on guide pin extending inwardly from side wall 2. A coil spring 2M- has one end attached to the lower end portion of push-button control slide 292 and the upper end secured to guide plate "EU! for normally holding push-button control slide 282 at-its upper limit of sliding movement. The lower endof push-button control slide EH32 is provided with a lateral projection 235 for engaging arm 54 of control lever 4'? when push-button slide 202 is manually depressed to rotate control lever ll in a clockwise direction on the pivot as shown in Fig. 2, and in a counter-clockwise direction as shown in Fig. 6, for operating micro-switch :3 to close the circuit for lighting the lights in the machine and also for releasing pawl 4 from clutch control ring 46 releasing the clutch for engagement to feed film and expose the same without requiring the feed of documents. This manual control of the film feed and lights is provided for separating the photographic images of groups of documents on the film.

[as shown in Figs. 2 and 3 a counter is indicatcd at iilii having an operating arm 2% extending radially therefrom and connected at the free end to the upper end of operating link 2%.

he lower end of link 2&8 is connected to the armature of solenoid 2G9. Solenoid 2% is connected in a circuit to be energized each time a document passes through the feeding means for counting the number of documents photographed. A coil spring 2H3 has one end secured to a projection on operating link 2% and the other end secured to a pin mounted on the supporting bracket 2!! for the solenoid and the counter carried by side wall 2, as shown in Figs. 2 and 3. Coil spring 228 normally moves operating link 2B8 upwardly to its upper limit of movement while energization of solenoid 269 pulls the link downwardly to actuate the counter.

A laterally extending pin H2 is mounted on the upper end portion of operating link 268 and extends inwardly toward side wall 2 as shown in Fig. 3. Push-button control slide 202 has an actuating 2 i ii on the upper end portion thereof as shown in Fig. 2, extending laterally to engage the inclined end on the L-shaped retaining slide 2! slidably mounted on a pair of guide pins extending outwardly from side walls 2 so that the opposite end will be projected under late-rally extending pin 2 E2 on slide 263 whenever push-button control slide 202 is manually actuated into a depressed position. This operation of retaining slide 2M retains operating link 268 in the upper position so that energization of solonoid 289 will not operate the counter. A coil spring 2H: secured under tension between a pin on retaining slide 2M and one of the guide pins for the slide normally moves the retaining slide to the left, as shown in Fig. 2, into a position where it does not interfere with the normal 0pcration of operating link 2823 by solenoid 209. This condition exists when push-button control '16 slide 282 is in the upper position shown in Fig. 2.

The rotation of indicia drum iii] and the operation of the mechanism thereon is controlled by five push-button operating slides 228, 225, 223 and 22 3 respectively, as shown in Figs. 6 to 9. Each of these push-button operating slides 2223 to 22 1 inclusive is slidaloly mounted against the inner face of control plate Elli in spaced parallel inclined relation, parallel to pushbutton control slide 202 and with the upper end of each slide slidably engaged in and extending through slots formed in guide plate Elli with intermediate portions below guide plate 26! slidably engaged on guide pins 225 extending inwardly from control plate 2%. Each of these push-button operating slides is of similar construction but varies in length in the manner shown in Fig. 6.

Push-button operating slide 22 3 is at the front of the series and at the front of the machine, as shown in Fig. 6. An operating pawl 22E is pivotally mounted intermediate its ends on the lower end of push-button operating slide 22 5 and normally rotated in a clockwise direction as shown in Fig. 6 to have the lower end engage limiting pin 22? by a tension coil spring 228 connected at opposite ends to the upper end of operating pawl 226 and guide panel 2M. The lower end of operating pawl 226 is adapted to engage latch member 2559 pivoted on stud 23%! and normally operated in a counter-clockwise direction as shown Fig. 6 by coil spring 235 connected at opposite ends to one arm of the latch member and guide plate 2%. This spring operation of latch member JEQ normally acts to engage the lower end of latch member 229 with laterally extending pin on the intermediate portion of advancing bar 233 pivoted at its forward end on pivot stud 234. In the position shown in Fig. 6 the latching shoulder on the lower end of latch member 228 engages under pin E32 and normally holds numeral advancing bar in an upward rearwardly inclined position. as shown in Fig. 6, where it is inoperative to cause an advance or operation of the numeral displaying unit l2ll. A coil spring 235 has one end connected to numeral advancing bar 233 and extends downwardly therefrom for connection at the opposite end to a stud on control plate 208 for normally applying tension to operate numeral advancing bar .233 in a clockwise direction to move the rear end downwardly until it engages positioning disc 23% mounted on a holding stud 23? extending inwardly from the inner face of control plate 2% near the lower end thereof. Latch member 228 has a rearwardly and upwardly extending projection adjacent stud 2E3 aligned with the lower end of operating pawl 22$ for engagement thereby when push-button operating slide 22 3 is manually depressed or moved downwardly.

Manual operation of slide 224 will rotate latch member 229 after engagement of operating pawl 226 therewith to move it in a clockwise direction as shown in Fig. 6, for disengaging the shoulder on the lower end thereof from pin 232. This allows spring 235 to move numeral advancing bar 233 downwardly into engagement with positioning disc 236 for positioning the rear end of bar 233 to engage operating pin M9 on advancing lever it? as indicia drum H3 rotates with main drive shaft H, as shown in dotted lines in Fig. 4. In the continued rotation of the drum from the position of advancing lever Nil and numeral advancing bar 233 shown in Fig. 4 in dotted lines, pawl I56 will be operated'to engage 17 ratchet Wheel I29 and advance unit number wheel I38 one digit by partial rotation thereof with shaft I26.

As soon as advancing lever I41 has been rotated on pivot stud I48 to an extent sufficient to advance unit numbering wheel I30, one digit, the inner end of lever M'I will engage guide pin I5I- and have its movement limited thereby so that upon further rotation of indicia drum I'II! operating pin M9 of lever I4I will move the rear end of numeral advancing bar 233 upwardly about its pivot until laterally extending pin 232 is above the shoulder on latch member 229 whereupon the latch member will move into the full line position shown in Figs. 4 and 6 and latch numeral advancing bar 233 in an inoperative position. At the completion of this movement of numeral advancing bar 233 pin I49 will move beyond the end thereof and continue rotation with drum IIIl. Spring E52 will move advancing lever I41 and pawl I50 back into the position shown in full lines in Fig. 4 ready for the next digit advancing operation.

If push-button operating slide 224 is manually held in a depressed position for more than one revolution of main drive shaft II and indicia drum III], numeral advancing bar 233 will remain in an operative position for engaging and advancing unit number wheel I30 one digit for each revolution of indicia drum I Iil and accumulate the numbers on the several number wheels, by the operation of the several number wheels in a manner hereinabove described in connection with the description of the structural features of number displaying unit I20. When pushbutton operating slide 224 is pushed down and immediately released, numeral advancing bar 233 will be released and secure only one operation of the number displaying unit E25 so as to advance the number only one digit which is ac-.

number desired and manually setting date unit I 2| and location designating units I22 and I23.

Thi means requires the rotation of the drum to be stopped during the setting operation of the various units thereon and for this purpose the drum must be stopped in different positions in order to provide for a single setting member to be used. For this purpose mechanism is provided for engaging stop pins I94, I95 and I96. This mechanism is controlled and operated by pushbutton operating slides 220, 22!, 222 and 223.

An operating plate 245 is formed with transversely extending slots slidably receiving guide projections 24I extending inwardly from control plate 205 between the push-button operating slides, as shown in Fig. 6. Operating plate 240 is slidably mounted against the inner faces of push-button slides 220 to 224 inclusive in spaced parallel relation below guide plate 2M for slidable movement transversely across the push-button operating slides and at right angles to the sliding movement thereof.

Operating plate 240 is apertured in transversely aligned relation in registry with push-button control slides 220, 22I and 222 as indicated at 242, to provide slide control projections 243. Apertures 242 are also formed to provide inclined cam faces 244 on operating plate 240 at the lower ends of apertures 242. Each pushbutton operating slide 225, 22I and 222 is provided with a laterally extending operating pin Lil 245 projecting through one of the openings 242, as shown in Fig. 6. Operating pins 245 are located in the same corresponding position on each of the operating slides 220, 22I and 222. Each of these push-button operating slides 229, 22I and 222 also has a second operating pin 245 extending laterally therefrom in equally spaced rela tion below pins 245 through cut-out portions of operating plate 240 formed in a manner so that they will not interfere with the lateral sliding movement of the operating slide on guide projections 24l.

Push-button operating slide 223 only has one operating pin 24l' mounted on the lower end portion thereof and extending laterally through a cut-out portion in the lower front portion of operating slide 24 as shown in Fig. 6. Operating slide 240 is formed with an inclined cam face 248 on a central front edge portion below the position of operating pin 241 when it is in the inoperative position as shown in Fig. 6, for engagement by said pin in downward movement thereof when operating plate 240 is in the opposite limit of sliding movement from that shown in Fig. 6 such as illustrated in Figs. 7 to 9 inclusive. A plurality of tension coil springs 243 have the upper ends secured to guide plate 22I in spaced relation and arranged to have the lower end of each spring attached to one of the second operating pins 246 and operating pin 241. These coil springs 249 will normally be under tension to hold push-button operating slides 220 to 223 inclusive in an inoperative position at the upper limit of movement at shown in Fig. 6.

A holding pawl 25B is pivoted on the inner face of operating plate 240 intermediate its ends and has a lateral depending extension on the forward end arranged to engage on the upper periphery of operating pin 24'! on push-button operating slide 223 in the inoperative position thereof. The opposite end of holding pawl 250 has one end of coil spring '25I secured thereto with the opposite end secured to an inwardly extending pin on control plate 20-0 to the rear of operating plate 240 and adjacent'the upper corner thereof in the inoperative position. Spring 25I is normally tensioned to rotate holding pawl 250 in a counter-clockwise direction as shown in Fig. 6, so that when operating plate 240 is moved to the left from the position shown in Fig. 6 to the positions shown in Figs. '7 to 9 inclusive the depending lateral extension on the free end thereof will move downwardly in front of operating pin 24'! and retain operating plate 240 in the position shown in Figs. '7 to 9 inclusive, against the tension of spring 25I tending to return it to the position shown in Fig. 6.

The lower rear portion of operating plate 240 is formed to provide a beveled edge 252 to provide an operating cam for engaging the complementary beveled projection 253 on holding lever 254 pivoted at the forward end opposite projection 253 for vertical sliding movement on pivot pin 255 carried by holding lever supporting bracket 256 mounted on control plate 200 and having upper and lower end portions and an intermediate projection extending inwardly in spaced parallel relation from control plate 200 to receive and support pivot pin 255 at the upper and lower ends and the intermediate portion thereof. A coil spring 251 encircling pivot pin 255 engages between the intermediate portion on bracket 258 and the upper front end portion of holding lever 254 for normally holding lever 254 at the upper end of its sliding movement any of'the stop pins i9 3, I95 or I95.

' ment with I shaft 263.

supporting .Spring 259 is normally tensioned to move the rear end of holding lever 254 outwardly so that the outer face thereof will engage the inner face of control plate 2% and thereby move holding projection 258 outwardly to engage the left-hand side wall 2 so that the end will not engage with It will be understood however that holding lever 25 in the upper position on pivot pin 255, as shown in fig. 6, will have holding projection 258 arranged in alignedv position for engaging stop pin i9 5 spaced. radially outward from shaft H the greatest distance. This is indicated in Fig. 6. However, when holding. lever 2fili is in the position shown in Fig. 6 with the rear end held up against control plate Zliil, coil spring 259 holds this plate in a position so that holding projection 258 will not engage stop pin I94, but in the rotation of the drum, pinISfl will move past the inner end of holding projection 258.

Bracket 266, Fig. 10, has the ends of the legs secured to the outer surface of sidewall 2 with the central portion of the bracket. offset outwardly to the left of side wall. 2. in spaced relation. Thebottom portion of. a cup member EGI 'issecured to the central offset portion of bracket 268 with the outer open end abutting'the inner edge of left-hand side wall 2 of the casing. The left hand-side wall of the casing has an aperture formed therein. as shown in Fig. 10 to provide' manual access to the inside of cup member 265' for. gripping handle 2B2. Handle 252 is mounted on theouter end of shaft 263 extending through registering apertures in bracket 260 in the bottom of cup member 25I and having a setting member 264 in the form of a sleeve rigidly secured thereto for sliding and rotating movesleeve member 294 is formed with an annular flange 235 for engaging the central oil'set portion of bracket 260 to limit the outward sliding movement of sleeve 254. and shaft 263 under the operation of compression spring 266 engaged between fiange Zfifi and the'outer face of left-hand side wall 2 about setting sleeve member 264. The inner end of setting member 264 is formed with a pair of diametrically opposite setting projections 26? projecting inwardly in. parallel relation from the inner end. The inner end of setting sleeve member 264 is slidably engaged in an aperture in left-hand side wall 2 and is located in a position in spaced parallel relation to the axis of main drive shaft 5! having the radial distance between the center of main drive shaft-ii and the center of sleeve 264 equal to the radial distance of the centers of shaft I26 of number displaying unit I26, sleeve I63 of date unit I2i, and

shaft I85 of location'designating unit I23. Therefore, whenever one of these shafts on indicia drum H0 is in axially aligned relation with setting sleeve member 264, handle 262 may be manually gripped for slidably moving shaft 253 and setting member 264 inwardlyto engage setting The outer end of setting 26 projections 26'! in the recesses in the end of the shaft on indicia drum III] in aligned relation therewith so that rotation of the handle will rotate the shaft of the engaged unit for settingthe indicia thereon.

Setting member 264 is prevented from inward movement to engage any of the shafts on indicia drum Q if by means of a guard projection 258' (no tending downwardly from the lower forward central portion of operating plate 240 and having the lower end in the position of plate .249 in. Fig. 6 overlying the end of setting sleeve member 265. This guard projection prevents operation of the setting member while drum H6 is rotating.

Whenever electric switch 269, Fig. 1, mounted on the front upper corner of right-hand side wall I is manually operated to close the circuit thereto-for starting the motor and setting the machine in operation, the push-button operating slides can then be operated for changing the seti ting of indicia on indicia drum I I 0 inthefollowing manner.

In the normal operation of the machine, main drive shaft I! will be continuously driven for feeding and photographing any documents inserted into the document feed mechanism at the upper end thereof. Indicia drum l ID will be continuously driven by the clutch structure with shaft H. The position of the indicia at the periphery of indicia drum I Ill is arranged so that the indicia move at the same surface or lineal speed as the documentsbeing fed through the machine for photographing. The indicia on drum III] are photographed as they are moved through the photographing position .at one side of the document being fed by the feed means.

When it is desired to change the setting of location designating units I22 and I23, the operator of the machine depresses push-button operating slide 220. As the. slide is moved down manually operating pin 245 will be moved downwardly into engagement with inclined cam face 284 at the bottom of aperture 242 and will move operating plate 2M5 forwardly or to the left as illustrated in Figs. 6 and 7, until pin 2G5 reaches the bottom of the cam. Inthis position the depending lateral extension on the free end of holding pawl 25!} will. move downwardly in front of. operating pin 2 3? and. hold operating plate 240 in the position shown in Fig. 7-. When pushbutton. operating slide 220 is released coil spring 249 thereon will pull the slide backupwardly until operating pin 245 engages slide control projection 243. Push-button slide 229 will therefore-be held in a depressed position corresponding to that shown in Fig. 7.
